Back contact type solar cell

The utility model relates to a solar cell sheet, in particular to a back contact type solar cell sheet, which comprises a connecting column, a first cell sheet and a second cell sheet are respectively connected with the left side surface and the right side surface of the connecting column, and a connecting structure is movably arranged in the connecting column. According to the back contact type solar cell, the first cell and the second cell which are not associated with each other are tightly connected through the connecting structure, the protection plate is inserted into the top of the H-shaped connecting column, the rotating nut is rotated, the bottom of the nut drives the rotating shaft to rotate, and the protection plate is inserted into the top of the H-shaped connecting column. A rotating shaft is rotated to drive a gear to rotate, and the gear is engaged with a rack on a protection plate, so that the protection plate drives a first battery piece and a second battery piece to be inserted into a connec
